Since the multiplayer megapacket update, being in battle has resulted in what seems like input lag. Im not alone in noticing this, it makes dodging spit and retreating into 1x wall opening near impossible. Below is a test i conducted by spinning up one of our servers and joining it( (left) pre mega (right) post mega, i also made a keyboard macro to move left to right at a consistent rate. I started each test out of battle mode and entered it by shooting a wall, notice at the end there is a jump and end up in sync once again, there is no edit.
